  1. 11. Assessing edge pixel classification and growing stock volume estimation in forest stands using a machine learning algorithm and Sentinel-2 data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Enzo Zerega; [2018]
    Keywords : Physical Geography; Ecosystem Analysis; Random Forest; remote sensing; accuracy assessment; land cover classification; training stage; multi-temporal; edge areas; Earth and Environmental Sciences; Science General;

    Abstract : Sustainable forest management requires accurate and up-to-date baseline data regarding forest structural parameters and the definition of forest stand units. A crucial component in stand characterization is the identification of tree species and to correctly define the stand boundaries. READ MORE

  3. 12. Tree species classification using multi-temporal Sentinel-2 data

    University essay from SLU/Dept. of Forest Resource Management

    Author : Magnus Persson; [2018]
    Keywords : sentinel-2; tree species; random forest; recursive feature elimination;

    Abstract : The Sentinel-2 program provides the opportunity to monitor terrestrial ecosystems with a high temporal- and spectral resolution. In this study, the utilization of multi-temporal Sentinel-2 imagery and it’s spectral variation due to phenology for classification of common tree species is evaluated at the forest estate Remningstorp in central Sweden.

  4. 13. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Cecilia Borghero; [2018]
    Keywords : SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Abstract : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. READ MORE

  5. 14. Comparison of multi-temporal and multispectral Sentinel-2 and Unmanned Aerial Vehicle imagery for crop type mapping

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stephania Zabala Ramos; [2017]
    Keywords : classification; Random Forest; precision agriculture; UAV; remote sensing; Micasense; GEM; Earth and Environmental Sciences;

    Abstract : Precision Agriculture aims to maximize crop production and the efficiency of land use to meet the increased demand for food while minimizing environmental impact and economic cost of food production. Crop type maps are needed for Precision Agriculture applications and remote sensing techniques are an efficient way to produce this information. READ MORE

  6. 15. Joint use of Sentinel-1 and Sentinel-2 for land cover classification : a machine learning approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Miguel Gumersindo Castro Gomez; [2017]
    Keywords : Random Forest; temporal series; Physical Geography and Ecosystem analysisoptical; GEM; land cover classification; SAR; Earth and Environmental Sciences;

    Abstract : Reliable information on land cover is required to assist and help in the decision-making process needed to face the environmental challenges society has to deal with due to climate change and other driving forces. Different methods can be used to gather this information but satellite earth observation techniques offer a suitable approach based on the coverage and type of data that are provided. READ MORE
